This invention relates to improvements in window screens and embraces ascreen frame adapted to be pivotally mounted along one of itslongitudinal edges in a window casing 5 and provided with mechanismassoclated with the window frame and the screen frame to facilitatemounting of the screen frame and latching of the same from the interior.

It is an object of this invention to provide a window screen frameconstructed of interfitting inner and outer frame sections between whichthe screening is adapted to be clamped. v I

' It is also an object of this invention to provide an improved screenframe having a sleeve integrally formed'along one of the longitudinalmembers thereof to carry pivot pins for pivotally mounting the screenframe in a window frame.

It is a further object of this invention to provide an improved screenframe adapted to be pivotally mounted in a window frame and having ashiftable latch plate mounted on v the inner side ofthe frame adapted tobe moved into latching engagement with a latch plate secured to thewindow frame.

It is furthermore an object of this invention to provide an improvedscreen frame having pivotrpins engaged in the end of one of thelongitudinal members of the frame to facilitate pivotal mounting of thescreen frame in a window frame by means of an improved bar and bracketarrangement mounted on the sill member of the window frame.

' It is an important object of this invention to provide an improvedscreen frame adapted to be readily mounted in a window frame to swingoutwardly on a vertical axis and having animproved bearing block for thereception of the lower pivot pin of the screen frame, with said bearingblock adapted to be slidably mounted in position in a bracket secured tothe window frame sill to hold the screen frame in proper position topermit latching of the screen frame from the interior by means of animproved shiftable latch plate positioned for coaction with an aperturedplate secured to one of the uprights 5c of the Window frame.

TENT OFFICE Other and further importantobjects of this invention will beapparent from the disclosures in the specification and the accompanyingdrawings.

As shown on the drawings:

The reference numeral 1 indicates a wall of a building having an openingtherein in which a window frame or casement is mounted. The window framecomprises vertical side sills or upright frame members 2 and 3 connectedat their upper ends by a horizontal cross member 4. The lower ends ofthe framc members 2 and 3 are connected by means of a sill 5 providedwith a sill extension 6.

Securely mounted on the middle portion of the inner face of the easementsill member 3 is a latch plate 7 provided "with-aslot or opening 8 whichcommunicates with a slot or recess 9 cut in the casement sill member '3for the reception of a locking member hereinafter more fully described.

.Mounted by :means of screwsor I other suitable means .upon' theunder'surface atone end of the upper horizontal :member 4: of thewindowcasing is a bearing plate 10 ;provided with a pair ofscrew receivingapertures 11 (Figured) 'to facilitate mountingof thepiate. The bearingplate '10 is also'provided with a bearing opening 12 to receive theupperhearing :pin or stud 13 which projects from :the upper end of a tube orsleeve 14which isintegrally formed byrolling oneimargin ofthe flangeforming-a part of one-ofthe longitudinal members forming a partOfan-outer channel cross-sectioned screen frame 15.

The improved-screen proper comprises the outer channel cross .sectioned:meta'l screen frame '15 and an inner channel :cross sectioned metalscreen frame 16 which telescopes or fits into the outer screen fran'ieas indicated in Figures .6 and -9and stretches a wire screening'l 'l'tightly in position with the margins of the wire-screening clampedbetween the two interfitting screen :frames 15 and 16. Thetwo screenframes :16 and 15 are secured together by:means-.of;screws, bolts'orother suitable means.

Secured inithe lower end of the screen hinge tube 14 is a lower hingepin ors'tud 18 which is .adaptedto :be engaged .inz'a'socketornpening 19provided in a bearing 161001120. The bearing block 20 is slidablyengaged in a guide channel 21 integrally formed -'on an angle bracketi22secured :by means Lof screws 23 or other suitable means upon one end ofthe casement sill :5 as clearly illustrated in Figure "3. Thebearingblock '20 isprovided with an opening v 24; for the reception :ofa retaining :screw .25 to permit the bearing block when :in the positionillustrated in Figure 3 to be screwed in place inthe guidechannel 21toafford a'bearin'g for the'lower pivot pin 18.

In mounting the improved screen in position the upper pivot pin 13 isfirst engaged in the bearing opening 12 of the plate '10 after-which thelower bearing block is anoved into the dotted line position illustratedin Figure 3 to permit the lower pivot pin 18 -to be engaged in theopening '19 of-the bearing block 20 after which said bearing block ismoved into the full line position of Figure 3 and secured in place bymeans of the retaining screw 25. The improved screen is thus mounted ina hinge form in the window casement or frame with the outer screen frame15 positioned to the outside of the window.

Shiftably mounted on the middle portion of one :.of 'thellongitudinalmembers 0f the inner screen frame 16 is a screen latching devicecomprising a plate 26 one longitudinal margin of which is bent outwardlyat right .angles to afford a flange 27 the margin of which is bent atright angles to provide a latch flange .or .locking plate 28 adapted tobe moved into'latching engagement with the slotted :frame plate '7. The,-.guide or mounting plate 2610f :theflatch: device ;is provide with apair of :inclined slots 29 ure 7) .through which a pair of :mountingscrews3O project. .Integrally tformed-omthe upper .end -.of the mountingplate .26 of the latching device is aifingerpieceoranglememher-31 tofacilitate-a :shifting operation of the latching device. When thelatching device .is .in :the .full line position. illustrated in Figure.2 the latching plate .28 is :in released or unlockedposition as shownin .Figure 9 and is out of engagement with the slot 8-of the plate 7..The .screen is thus permitted to be .swimg outwardly on .the pivot pins.13 and .18. When the screen .is moved vinto closed position 'vvithinthe window ca-sing .it is adapted to be locked .in place by shifting thelatching device by means of the finger piece 31 downwardly .into thedotted line Tpositionof Figure .2 thereby projecting the latching plate.28 into ltheslot .8 .of the ,plate -7 to 110111 the screen locked inposition.

Figures v10 .and 1 1 of the "drawings illustrate a modified form ofscreen wherein .a wire screening 31 .is clamped in stretched positionbetween .two intenfitting channel cross sectioned screen frames each ofwhich is constructed .of. a ,pairof longitudinal channel .crosssectioned sills 32 and a -,pair of channel cross sectioned horizontal orvconnectingmembers 33. "The longitudinal .frame members 32 and thetransverse frame .member's '33 are connected together by means of a pairof .interfitting channel .cross sectioned corner ,plates or unions .34and 35. The .corner plates are providedwith integral tongues or lips '36which are .bent .at right angles to the plates35 -and ,pro' 'ec'tupwardly through slots or openings in the corner plates 34 and are "bentover to securlyfhold the corner plates '34 and 35 rigidly connectedtogether "to 'form a corner for the screen frame.

It will of course be understood that many changes may be made andnumerous details of construction maybe variedthrough=a'wide rangewithout departing from the principles of this invention, and itistherefore not pur I30 posed limiting the patent granted hereonotherwise than necessitated by the prior art.
